Depends on the computer
my laptop? when I'm not using it.
My all in one ? meh. I really don't like the thing so 2 months ago... the last time I used it... damn waste of money. I thought it would be a cool replacement for my venerable desktop but no. I hate it. I may power it up for its free windows 10 upgrade though lol.
My old ass desktop? ummmm there was a power blackout two months ago lol. In all the years I've owned it the computer has only been powered down when it was disconnected to move, being cleaned or when there was no power available. The last time I shut it off because it wasn't in use ..... yeah it has to be about 10 years now. Every computer I own is connected to "Old Bob" in one way or another.
